a really really old PU
very few are running now here, uSA.
key parts super hard to find.
Service manuals (SM)
the books back then, were only made from PAPER (500pages)
no digital books then (PDF) so buy the book used off EBAY?
books not fully digitized fully or ever at all, <<< not me, I PASS.
one way to find it is to know the pumps wire colors !
and the relay with those colors is BINGO
answer fuel pump relay (im reading the schematic now)
pins reiay coil are black/ and other wht/blk.
12vdc power in is ,blk/with ( 3 fuses good to get this hot)
pump pin wire is BLUE.
so that is one way and one answer.
googling fuse boxes 37 years old is in the IFFY category.
pure luck, and your job.
Car makers often use the same relay for different applications. The pump relay may be the same as the EEC, check the part numbers on the relay. Or go to ford dealership to get that relay.
sounds like the immobilizer is locking out the fuel pump,
have you replaced the key without reprogramming it?if so take the old key and the new tape them together at the tops cut portions facing in opposite directions and try starting the car that way the security light should go out
Dear Charlie,
May I suggest you take the car to a good (old?) mechanic and have it "changed?".
Right now the fuel pump is hooked to the battery directly, which is why the pump will not turn off.
Please have him hook the pump up so it only runs when the ignition is on.
God bless your efforts.
According to the information that I'm finding, the fuel pump relay on '94 Mustangs is part of the Constant Control Relay Module (CCRM). According to mustang-tech.org, the CCRM is the black box that's mounted on the radiator overflow. http://www.mustang-tech.org/wiki/94-95_Mustangs_Electrical_CCRM
